GENERAL DESCRIPTION
The FDC37M60x with IrDA v1.0 support
incorporates a keyboard interface, SMSC's true
CMOS 765B floppy disk controller, advanced
digital data separator, two 16C550 compatible
UARTs, one Multi-Mode parallel port which
includes ChiProtect circuitry plus EPP and ECP,
on-chip 24 mA AT bus drivers, two floppy direct
drive
support,
and
Intelligent
power
management. The true CMOS 765B core
provides 100% compatibility with IBM PC/XT
and PC/AT architectures in addition to providing
data overflow and underflow protection. The
SMSC advanced digital data separator
incorporates SMSC's patented data separator
technology, allowing for ease of testing and use.
Both on-chip UARTs are compatible with the
NS16C550. The parallel port is compatible with
IBM PC/AT architecture, as well as IEEE 1284
EPP and ECP. The FDC37M60x incorporates
sophisticated power control circuitry (PCC). The
PCC supports multiple low power down modes.
The FDC37M60x supports the ISA Plug-and-
Play Standard (Version 1.0a) and provides the
recommended functionality to support Windows
'95.
The I/O Address, DMA Channel and
Hardware IRQ of each logical device in the
FDC37M60x may be reprogrammed through the
internal configuration registers. There are 480
I/O address location options, Serialized IRQ
interface, and three DMA channels.
The FDC37M60x does not require any external
filter components and is therefore easy to use
and offers lower system costs and reduced
board area. The FDC37M60x is software and
register compatible with SMSC's proprietary
82077AA core.
